Climate scientists have observed the lowest temperature in a storm since using weather satellites until now. And they point out that this situation occurs frequently on Earth.
And the journal Geophysical Research Letters indicates that scientists were able to monitor this icy storm cloud, with a temperature of minus 111 degrees Celsius, using infrared images, which they obtained from a weather satellite.
And the lower layer of the atmosphere can become very cold at high altitude and can reach minus 90 degrees Celsius, and thunderstorms and tropical cyclones can be large, reaching a height of 18 kilometers, that is, they rise to the upper edge. of the troposphere.
Weather experts detect thunderstorms at high altitudes with the help of satellites, allowing them to monitor their movement and warn at the time of dangerous weather conditions. Because it is precisely because of these cold storm clouds that are located at high altitudes that the most terrible natural disasters occur.
It is reported that on December 29, 2018, the US satellite NOAA-20 flew over a strong storm 400 km south of Nauru, located in Oceania. As a result of its high intensity, this storm was able to penetrate the upper troposphere and reach the stratosphere, and continued to rise with the decrease in temperature despite the surrounding warm air, until it reached minus 111 degrees Celsius. The experts were able to record this score with the help of VIIRS (Visible Infrared Imaging Radiometer Suite) on the satellite.
“Since the height of the coldest part of this cloud does not exceed one kilometer, the position of the devices used in space orbit ensures that the high temperature of the clouds is measured very precisely,” said researcher Scott Bashmire of the University of Wisconsin in America at Madison.
Dr Simon Proud, principal investigator at the British National Center for Earth Observation, adds: “In recent years, temperatures from storms have decreased. Now we have to determine if this trend is related to climate change, or is caused by certain weather conditions, which in the recent period cause strong storms “, according to” Vesti. Ru ”.
